Abstract

A calibration device is connected to a sphygmomanometer with an air tube and a communication cable. When connection is detected, the calibration device closes a valve of the sphygmomanometer and its valve and applies pressure to the air tube to measure the pressure, and determines the air leakage of the sphygmomanometer based on the pressure change with an air leakage determination unit. The calibration device causes a pressure sensor of the sphygmomanometer to measure the inner pressure, receives the measurement result with the communication I/F, and determines the result of the equipment difference test of the sphygmomanometer based on a difference between the applied pressure and the inner pressure with an equipment difference determination unit. If determined that the equipment difference test is failure, a control signal is output to the sphygmomanometer to calibrate the output value of the pressure sensor in the calibration unit.
